The Hamilton Khaki is definitely a clean design, and it should work for pretty much any setting. I'd definitely recommend it as a solid choice in the $400-500 range. It's automatic, and it definitely looks better in person than in Amazon pictures.

Now that the weather has cooled off, I'm putting my lightweight (10oz) skinny guys into storage. They were worn about 50 times, and it seems I really only faded the crotch and fly.
The first picture has them laying on top of a new pair of left-hand twill 13.75oz, and the second picture shows the fading on the front.
